It did the trick, but when I bought it I was told that it had a '70 Police Interceptor engine. I have receipts for all the work done on it and was wondering if I could get some help interpreting it.

It shows a 1970 429 bored .30 over; Moly rings, balanced; Crank .010-.010; Cam 262-272;, 479-504 lift, etc.

Anybody know what the engine might actually be, and what kinda HP/Torque its putting out? I think I saw a D1VE on the block and C 8Ve-E on the heads.

Any help from the experts here is appreciated!
You do not have a 1970 439 Police Interceptor engine. The 429 Police Interceptor engine did not come out until 1971 and uses a different block casting number and different head casting number. The 1970 engine was a 428FE PI engine and is a completely different engine family.

Your heads are from a 1968 production 429 or 460 and the block is from a 1971-1978 429 or 460. Compression ratio is likely between 9.5:1 and 11.5:1 but we can't know for sure without a piston part number.
